There are currently over 730 different programming languages in the world. The list continues to expand every year. While some languages have been in demand for nearly 20 years, such as the C# and JavaScript, newer languages are becoming necessities.
Here are some newer programming languages that developers will need to know in the coming years.

Swift

Swift was developed by the team at Apple WWDC in 2014. Ars Technica published a detailed overview of the language shortly after it was released. It quickly became a major hit among developers.
Dice claims that Swift could grow faster than many of its predecessors over the next few years.

Google Go

Google Go was developed by several Google employees in 2009. It is an open source programming language with several benefits over its other C-based counterparts. Go is faster to compile and easier to learn.
Although this language is eight years old, it is starting to become more popular.

Coconut

Coconut is a functional programming language that was made as a competitor to Python. It compiles code right from Python, so you don't need to create a new interpreter to write and run your code.
InfoWorld praised the new language for introducing the functional programming features that Python programmers have wanted to see for years.
“Many of the new features exposed by Coconut involve more elegant and readable ways to do things Python already does. "Pipeline-style programming," for example, allows the arguments for a function to be submitted to the function with separate syntax. For example, print("Hello, world!") would be written as "Hello, world!" |> print. Lambdas, or anonymous functions in Python, can be written more clearly, such as (x) -> x**2 instead of lambda x: x**2.”

Oden

Google Go has a number of great new features, but some users have been disappointed. Oskar Wickstrom used its best to build Oden, an alternative to Go with better error-handling, nil-checking and control flow abstraction.
“The idea with Oden is to lift these restrictions and provide a more flexible type system, while also putting an emphasis on functional programming,”Wickström told InfoWorld.

Julia

Julia brands itself as “a high-level, high-performance dynamic programming language for technical computing.” It has built a strong following, although people from Software Carpentry and other agencies feel the language needs time to evolve.
While there are still clearly some kinks that need to be worked out, there are a lot of promising things about Julia. It has a number of Hadoop style features, which makes it a very useful programming language for developers working on big data projects.

Retrace

Retrace is the best new Relic alternative. There are a number of benefits, such as affordability and better logging features. It is also easier to use and specifically designed for pre-production.

Learn New Languages as the Future Evolves

Developers need to keep up with the times. New programming languages are always being adapted, which can be disruptors to the industry. While some of the core C-based languages aren’t going away anytime soon, they may take a backseat to newer counterparts for certain applications.
As a developer, you should begin learning these languages as soon as possible. Your career may depend on it in the next few years.
